CAN Controller in LM4F12x versus NXP CAN Controller in LPC11C24 same IP block?

Hi

At a first look, the register names for the CAN controller in the LM4F12X are the same as in in the NXP device.

Can somewone confirm that this is true, or not ?
It would make my work porting my CAN based firmware from the LPC11C24 to the LM4F a lot easier.

I need to have an 12 bit ADC, also, and for that the LM4F seems to be an ideal device.

If this seems to be the case, i think i will order the lauchpad EVK to get it tested.

kind Regards , Sagaert Johan

    Mon ami,

    Is what you're asking especially wise - or proper?

    Most here do not have quick/eased access to "brand X" - thus your satisfaction places some burden upon your assistants.

    And - is such "fast/furious" register "name" overlay/comparison really all that is needed?  (i.e. might the "bit-position encodings" w/in individual registers differ - thus dooming any such check - limited to simple "name overlap?")

    While the carrot/prospect of a single - sub 15 USD launchpad sale - surely commands great attention (dangles enticingly) - might this comparison be better performed by you? 

    Learning, familiarity & experimentation all are, "normal/customary" in such endeavors.  Short-cuts - especially those which are bit less than "well conceived" - may not serve your best interest...

    Just a quick follow up, i checked some of the registers and even the bits in the registers are the same, so i can be quite confidint in an easy migration to the LM4F12x .

    I suspect that the C_CAN block is the same for several different chip makers.
